, YARN HOLDER.

Application filed April 3,

To all whom it may concern:

Be it known that I, LoNns BLAIR, a citizen of the United States, residing at @211;- land in the county of Alameda and State of dalifornia, have invented new and us ful Improvements in Yarn Holders, of which the following is a specification.

This invention relates to the textile art, particularly to attachments for slashing machines, and has for its object the provision of a device for holding the yarn which passes to the large drum or slasher from the small sizing rolls of a slasher whereby to hold the yarn in a smooth even sheet and prevent twisting thereof when the slasher is stopped.

An important object is the provision of a device of this character which normally is in inoperative position, that is out of engagement with the yarn but which moves into and engages the yarn automatically upon movement of acontrol rod for stopping the slashing machine.

An additional object the provision of a device of this character which will be simple and inexpensive in manufacture, highly efiicient in use, durable in service, and a general improvement in the art.

"With the above and other objects and advantages in view, the invention consists in the details of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings in which- Figure 1 is a side elevation of my device associated with a slashing machine and showing it in normal or inoperative position.

Figure 2 is a similar view showing my device in yarn holding position,

Figure 3 is a plan view thereof, and

Figure at is a detail perspective view of my holder removed.

Referring more particularly to the drawings, l have shown my device associated with a slashing machine including a frame A upon which is journaled the usual large drum or cylinder B and a small. drum or cylinder C. Adjacent the frame A is located the size box D with which are associated the size rolls E. Yarn F is taken from the size box and passes through the size rolls E and then passes onto the drum B in a sheet-like arrangement. The operation of this machine forms no part of the present invention but the structure is 1922. Serial No. 549,053.

illustrated more or less diagrammatically for the purpose of making a clearer e3:- planation of the operation and utility of my invention. It should, however, be stated that in slashing machines of this character when the machine stops or is stopped the yarn is not properly held and consequently twists, a condition which is a distinct disadvantage and in fact a great trouble maker.

In carrying out invention 1 provide a yarn holder which comprises a rectangular frame including longitudinal bars it) which are preferably substantially elliptical in ,cross section, and which further includes end bars 11 secured to the bars 10. numeral 12 designates brackets which are secured upon opposite sides of the frame it. and the end bars 11 of my device are pivotally connected intermediate their ends, as shown at 13, upon the lirackets 15 Projecting from one end of one bar 11 is pin 14. upon which pivotally engaged the slotted end 15 of a link 16 which is pivoted intermediate its ends, as shown at 1?, upon the fame A ant which has its lower end pivotally connected, as shown at 18, with the shifting rod of the slasher.

Associated with each longitudinal bar 1) of my device is a roller 19 hav reduced ends 20 revolubly engaged within eyes or loops 21 formed in leaf springs secured to the bars 11. The rollers 19 are at opposite sides of the frame, clearly indicated in the drawings and it wll be apparent that these rollers are ibly supported so that they may be moved more or less toward the adjacent bars 10,

The operation of the device is as follows:

When the slashing machine is in opera tion and the shifting rod G is at one limit of its movement, the position of my device is as indicated in Figure 1, that is no part of my device touches the yarn. When the shifting rod G is moved to its other position and the slashing machine is stopped, the movement of the rod G will cause movement of the link 16 and this will result in swinging the frame of my device so as to press the rollers 19 into engagement with the yarn F and they will of course hold the yarn in its sheet-like arrangement and prevent its twisting.

From the foregoing description and a study of the drawings it will be apparent that I have thus provided a simply con- Thc structed and easily installed attachment to a slashing machine which will operate entirely automatically to engagement or disengage the yarn, depending upon whether the slashing machine is out of or in operation. Owing to the simplicity of the struc-- ture it is apparent that the device will be inexpensive and that there will be nothing to get out of order.

lVhile I have shown and described the preferred embodiment of my invention, it is of course to be understood that I reserve the right to make sch changes in the form,construction and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention I claim;

1. In con'ibination with a slashing machine including a drum onto which yarn passes, a size be); provided with rollers between which the yarn is fed, and. further including a shifting rod; a yarn holding device comprising a rectangular frame of elongated shape disposed transversely of the slashing machine and pivoted at its ends, the longitudinal axis of said'frame being transverse with respect to the path of the yarn, rollers journaled at the longitudinal sides of said frame, and means connected with said shifting rod and with said frame whereby to tilt the latter to bring the rollers thereon into engagement with the yarn when the shifting rod is moved to stop the machine.

2. An attachment to a slashing machine including a drum onto which yarn is fed from a size box, comprising brackets secured to the frame of the slashing machine, a rectangular frame including longitudinal bars and end bars, said end bars being); pivotally connected intermediate their ends upon said brackets, a pivoted link connected with said frame and with the receiving rod of the slashing machine. rollers located above and below the respective longitudinal bars of the pivoted frame spring pressed outwardly away from the frame and engageable with the yarn when said frame is tilted by movement of said link when the slashing machine is stopped.

3. In combination with a slashing machine including a drum onto which yarn passes, a size box provided with rollers between which the yarn is fed, and further including a shifting rod; a yarn holding device comprising a rectangular frame of elongated shape disposed transversely of the slashing machine and pivoted at its ends, the longitudinal axis of said frame being transverse with respect to the path of the yarn, rollers journaled at the longitudinal sides of said frame,

and means connected with said shifting rod and with said frame whereby to tilt the latter to bring the rollers thereon into engagement with the yarn when the shifting rod is moved to stop the machine, the rollers being mounted on the frame by means of springs which normally press the rollers away from the frame In combination with a slashing ma chine including a drum onto whichyarn is fed from a size box, and further including a shifting rod for stoppingthe machine; a yarn holding device comprising upstanding brackets mounted upon the frame of the slasher, an elongated rectangular frame having its shorter sides pivoted intermediate their ends upon said brackets, the frame be- .ing arranged with its longitudinal bars transverse with respect to the travel of the yarn,a pair of spring pressed rollers journaled on the frame in spaced relation to the longitudinal bars thereof, said rollers being arranged one above and the other below the frame and the yarn being threaded through the frame whereby to be above one roller and below the other, and means connected with the frame and the shifting rod whereby to tilt the former to bring the rollers into engagement with the yarn when the shifting rod is moved to stopthe slasher.

In testimony whereof I afiix my signature.
